Login with device does not work. API Error

[JonnyFPV]

Hi,

i want to use the login with device feature.

I get the popup on my devices, tap on the accept login button and then I get some error.

Log shows this:
[2023-09-03 13:03:46.897][vaultwarden::api::core::accounts::_][WARN] Data guard Json < AuthResponseRequest > failed: Parse("{"key":"4.LQmkQMm6tiiQ6Vz8LOgBPi3WbVPI1FjlllkkdjhhbfmKci69WNMlQYZc7ufn29VDrP6SC8CriWYBsUn5l0IXXBUyV6m7Ize/Ra3Pws3FiWFdZc6UO1kybu6zRmEeZGV+D/GXl9GqGbRJk9wkV1w/Zmh99Sh0ETmNw04q9NvObkg2lyLmiBweDeVZXutQ13ynPmsrbmkUHfR+wDSzIJdk8eCz0A/wV/Q/6Nql+G6WyVdCYn5We4HKGJRxPnye05hwQf8rH48BSBsetGxIFS8y7BeuIPmSwxi/6dKI8GFZpWrfczWZr8sX9hXSIUym9G9oaRpTJaP/laOGb8W1s8/c7svUXw==","masterPasswordHash":null,"deviceIdentifier":"ae20de96-e508-4a5b-91ea-d68d7c66d21c","requestApproved":true}", Error("invalid type: null, expected a string", line: 1, column: 381)).

Using proxy with Traefik v2 if it matter. Push notifications work.... only this new login method not. ###

any ideas?

regards.

ps: I changed the showed keys here in this error log.
